Summary:                    Asterisk not send fax to fax extension
Description: 
Asterisk isnt sending fax to fax extension:

== Redirecting 'SIP/69.167.68.134-00000036' to fax extension due to CNG
detection
 == Spawn extension (from-trunk, fax, 1) exited non-zero on
'SIP/69.167.68.134-00000036'

---------------------------------------------------------------------- 
I also run into this issue; I posted on asterisk-users and asterisk-dev on
2010.11.13

I upgraded from a perfectly working 1.6.2 asterisk installation
(including fax via app_fax_digium) to 1.8.0 -- and fax functionality has 
broken.

When a fax caller connects, asterisk detects the CNG, logs a message 
about switching to the fax extension, but then hangs up the call.

i have:
  exten => fax,1,NoOp( got to fax extension )
  exten => fax,n,Goto(fax,rx,1)

I never receive the noop message.

i've captured with:
   core set verbose 10
   core set debug 10
   fax set debug on
   sip set debug peer vgw1

(vgw1 is my cisco 1760 ata)
